IMPROVEMENT IN'V VPCUNTAIN-PEN'SL i-M The Schedule referred to in' theseLetters'Pateht and making part of the same B, soethat a light or heavymark maybe made in writ- To all whom 'it may concern:

Be it known that I, ALBERT S. GARLETON, of Providence, in the county ofProvidence and State of Rhodey Island, 'have invented a new and usefulImprovementn Stylus for`Handwriting; and I do hereby declare that the4following is a. full, clear, and exact-'descriptionthereo', which )villenable others skilled inv the art to make and use the same, referencebeing had to the accompanying drawing forming part of thisspecification.

' The object ofthis invention is toprovide asubstitu'te for the ordinarywriting-pen, whereby a constant supply of ink may be always ready foruse, and by which alight or heavy and uniform ink-niark may be made onpaper; and It fmnsists` in an inkft'oitain tube, tapered nearly lto apoint at one end, and discharging the ink therefrom, the flow of' ink'being regulated by an adjustable needle-valve, and by Van adjustableair-valve or screw, as hereinafter more fully described.

The accompanying ldrawing represents a magnified longitudinal section of`a writing-stylus constructed accordingto my invention.

Similarletters l'o'treference indicate corresponding parts.

represents a tubev (of metal'or'other suitable ma' terial) in two parts,,connected together by screwthreads, as'seen at B.

The upper portion of this'tube (marked C) is an air-chamber. Y v

' The lower portion D is an ink-reservoir or fountain.

The extreme end terminates ina delicate tube,

formed of' metal, or of any non-corrosive material or composition.Thisvlight tube c forms the writing-point, the ink from the reservoirbeing discharged therefrom.

f-isthe vstem of the needle-valve g.v The stem fis 4conuected'with thebottom of the air-chamber O, and, when the two parts of the stylus arescrewed tightlytogether, as represented in thedrawing, the tube e isclosed, so ,that no ink can escape..

lThe valve is regulated byuriscrewing the tube at ing, as may bedesired.

This needle g keeps the tube e clear of sediment at Iall times, 'andallows a free ilow of ink through it.

But the flow of ink is dependent, in a great measure, upon the pressureof the atmosphere. This pressure is regulated by means of the splitscrew, H, in 'the end of the air-chamber. By turningthis screw, air isadmitted to or shut off from sthe air-chamber C.

Throughjthe bottom of the 'air-chamber there are one or more holes, t',through which air passes from the air-chamber to the'ink-reservoir.

J represents' a cap for protecting the point of the stylus when it isnot in use. This cap contains sponge or some other suitable substancefor absorbing any .ink whibh m. y be left on the point after writing, or

which may, by any pos sibility,leal'i through `the tube.

This substance K also acts as a stop-to thelow of, therink throughthetube when the air-chamber is re' moved fr filling the reservoir withink.

By this invention all the ldiliculties and inconveniences incident tothe ordinary methods of' writing arc overcome. Y

f The stylus may be carried in the pocket, ready for use at all times,and, as no pressure is required -in forming 'the letters, it may be`used iu sitl1atious'-ivliex'e an ordinary pen would beuseless.'

Having thus described my invention, y l

I claim asv nwand desire to secure by Letters Patent- A stylus forwriting composed of the vtube A, formed in two parts, C D, the firstbeing auair-chamber, and the second an ink-reservoir, the auxiliary'tube e, andthe needle-valve j' g, all constructed, operated,

and fittedtogether in the manner described.

Theabove specieation of my invention signed by me this 20th day ofOctober, 1860.

i A. S. GARLETON.
